"Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?"
"He that doeth the will of my Father which is in heaven...shall enter into the kingdom of heaven."
"Wherefore by their fruits ye shall know them."
"The axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire."
Matt. 7:16-21 & 3:10
